It's really pretty simple, if you don't like FB's practices then just don't use FB. I imagine a lot of other sites do the exact same thing but they just aren't big enough to have anyone take notice. I suspect a lot of apps we use on our phones and tablets do the exact same thing and even more but we just don't seem to notice. I suspect we have already started down the slippery slope with laws and privacy years ago and are hurtling down the slope at break neck speed with no way to stop.
